My partner and I have recently decided to try opening up the relationship a bit. We've been together for 8 years, and our communication is solid. We both know what we want, and we're definitely on the same wavelength about the baby steps we're taking to ensure we're both comfortable. With all of that said, I would like to get to my current situation: I have my first legitimate crush. I have not felt this way since, well, 8 years ago. I'm worried that this new and exciting person will overshadow my love for my current partner. My partner is not worried at all, because I have so much love to give all the time, but I'm scared of the unknown. My partner is very encouraging, and is even amused with my twitterpated self. It's fun, for sure, but I'm still afraid for what it's like to feel so strongly for two people at once. Make no mistake; I'm not "in love" with this new person (like with my nesting partner), it's simply infatuation. However, it's definitely a strong infatuation! Like, all consuming. Sometimes it feels like there isn't room for the love I already have, and that's what truly scares me. Nothing has happened with this person yet aside from movie nights, cuddles, and some flirting.

Can anyone give me some advice or some reassurance on this?

TIA, much love
